NEW YORK (

TheStreet

) -- Conan O'Brien is returning to television tonight as the host of his new show

Conan

on TBS.

O'Brien has been off the air since he left NBC in January after the network planned to bump his show to a later time slot to make room for

The Jay Leno Show

.

In June 2009, O'Brien replaced Jay Leno as the host of the

Tonight Show

after hosting NBC's

Late Night

show for 16 years. Leno's

The Jay Leno Show

aired during the 10 P.M. time slot and the

Tonight Show

aired at 11:35 P.M.

When Leno's show received disappointing ratings,

NBC executive Jeff Zucker

suggested pushing the start of

The Tonight Show

30 minutes later to 12:05 A.M., to make way for Leno's return to 11:35 p.m.

O'Brien would not agree to these terms. On January 21, it was announced that NBC would give O'Brien a $45 million exit deal, and O'Brien would no longer be a host on NBC.

"I sincerely believe that delaying the

Tonight Show

into the next day to accommodate another comedy program will seriously damage what I consider to be the greatest franchise in the history of broadcasting," O'Brien said in a January 22 statement. "The

Tonight Show

at 12:05 simply isn't the

Tonight Show

."

Tonight, O'Brien will appear on

Time Warner's

(TWX)

TBS, with Andy Richter as his sidekick. Actor Seth Rogen and

Glee!

actress Lea Michele will be his first guests, and Jack White will be the musical guest.

O'Brien's former

Late Night

and

Tonight

band leader Max Weinberg will not join him in his move to

Conan

. Jimmy Vivino, a guitarist and vocalist in the original band will lead the "Basic Cable Band" on the new show.

O'Brien's hour-long program is scheduled to air on weeknights at 11 P.M. ET. The show will begin about a half-hour before the start of

The Late Show with David Letterman

on

CBS

(CBS) - Get Report

and the

Tonight Show with Jay Leno

on

General Electric's

(GE) - Get Report

NBC.

Another late-night contender is

The Daily Show with Jon Stewart

, which airs at 11 P.M. ET on

Viacom's

(VIA) - Get Report

Comedy Central.

Stewart's

The Daily Show

was ranked as the No. 1 late night entertainment talk show among the 18 to 49-year old demographic in October, according to Nielsen.

Stewart brought in 1.3 million viewers between the ages of 18 and 49, while

The Tonight Show with Jay Leno

and the

Late Show with David Letterman

tied with 1.2 million viewers each.

With

Conan

set to debut tonight, many television watchers anticipate the November results. With

Conan

on the air there will likely be increased competition among the late-night programs.

Now we'd like to know what you think. Will you be watching Conan on TBS tonight? Or will you stick to your usual programming on CBS and NBC? Take our poll, and see what readers of
